Read Grace for President
Show map showing votes (red=republican, blue=democrat)
Make slips of paper with state names. Each student gets one or two, depending on class size.
Students find their states on the map and notice what color is represented.
Introduce Coke and Pepsi. Perhaps have a taste test.
Each student casts his/her state's vote based on preference for Coke or Pepsi.
Use the interactive map to show results.
